Description

Die bisher auf .den Markt gebrachten Laubsägen für Bastler und Schreiner haben den Nachteil, daß die Laubsäge mit der einen Hand geführt, mit der anderen das zu schneidende Holz gehalten werden muß. Hierdurch entstehen keine geraden Schnitte und die Schnittkante muß durch Gradfeilen korrigiert werden.The fretsaws for hobbyists and joiners that have been brought onto the market so far have the disadvantage that the fretsaw is guided with one hand and the other the wood to be cut must be held. This means that there are no straight cuts and the cutting edge must be corrected by filing.

Diese Mängel werden durch die nachfolgend beschriebeneaiiliüge in Abb. i bis 4 behoben, und zwar zeigt ebb. 1 die I...ttibsäge von der Seite, teilweise geschnitten.These deficiencies are highlighted by the below-described lie in Fig. I to 4 corrected, namely shows ebb. 1 the I ... tibsäge from the side, partially cut.

A11.2 eine Ansicht, teilweise geschnitten, in Richtung a-a der Abb. i, Abb.3 eine Draufsicht auf den Arbeitstisch mit eingelassener Führungsscheibe und A11. 4 eine Ansicht der vorderen Führung in. Richtung D der Abb. i.A11.2 a view, partly in section, in the direction a-a of Fig. i, Fig.3 a top view of the work table with an embedded guide disc and A11. 4 shows a view of the front guide in the direction D of FIG.

Mit b ist der T-förmig ausgebildete Laubsägebogen bezeichnet, der an einem Arbeitstisch i mit Hilfe von vier auf Bolzen laufenden Führungsrollen e# in einer Vorrichtung auf und nieder bewegt werden kann. Die Vorrichtung ist mit Hilfe einer Klemme am Arbeitstisch befestigt. Ferner gleitet der Laubsägebogen in zwei Fiihrungsbolzen f, zwei 1,- edern g liegen um sie herum und drücken den Bogen b nach oben. Der Bogen trägt außerdem an seinen Enden oben und unten je eine dreh- und feststellbare Sägeblattführungsklemme c, die mit einer Flügelschraube am Bogen b angeschraubt ist und das Sägeblatt aufnimmt. In den Arbeitstisch i ist eitle abnehm-, dreh- und feststellbare besondere Führtingsscheibe lt eingelassen, die entsprechend der Sü,gelTlattführun,gsl;lemmen c versetzt wird, um dadurch das Sägen in den Richtungen E, l,, G zu ermöglichen (Abb. 3, Draufsicht C), ferner befindet sich hier ein Führungsbolzen f ohne Feder.With b of the T-shaped fretsaw is referred to, the on a work table i with the help of four guide rollers e # running on bolts can be moved up and down in a device. The device is with Attached to the work table with the help of a clamp. The fretwork arch also slides in two guide bolts f, two 1, - edern g lie around them and press the bow b up. The bow also has a rotating top and bottom at its ends. and lockable saw blade guide clamp c with a thumb screw on the arch b is screwed on and takes up the saw blade. In the work table i is vain removable, rotatable and lockable special guide disc according to embedded, the corresponding the Sü, gelTlattführun, gsl; lemmen c is offset, thereby making the sawing in the directions E, l ,, G to enable (Fig. 3, top view C), there is also a guide pin here f without spring.

Durch einen einfachen Fuß- bzw. Motormechanismus wird dieLaubsäge nach unten in Richtung B gezogen und durch Federkraft wieder in die urspriingliclie Lage gehraclit.With a simple foot or motor mechanism, the jigsaw pulled down in direction B and returned to the original position by spring force Location gehraclit.
